Hi all,
I saw there was talk of usrp2, is that new digitizer hardware, or new
software for the existing USRP ?
In case it is new, maybe it is a good idea to take two FPGA’s aboard
the machine, such as to be able to do signal processing on one, and
leave the other preprogrammed when no need to adapt the standard signal
processing and interfaces.
In fact there are even development boards with built in FPGA with
significant capacity which could be interesting like this TI one:

Is it hard to make a generally usable ethernet or Usb connection to
yield the high bandwidths needed for signal input, or is it a matter
of industrial interest that such units (as exist for disk drives
and such) are hard to get, and also not easily makeble from the sr
sources?
The same for the receiver design: am I istaking or are even the open
diagrams deliberately hard to read in aspects and containing less
regular parts? In the HAM world it isn’t considered a crime to make
ones own hardware and usually seems not to interfere with business
interests too much, or is the IT world in the way?
Kind Regards,
Theo V.
